The main pict is generated by AI and a misleading hallucination, or as we use to call it "totally wrong".

I'm not a geologist, so I have to take a few guess to read the main paper https://www.science.org/doi/10.1126/sciadv.ady8347

When the slab in the subsection one goes under another slab, it does not get destroyed, but goes down quite intact. But from time to time (every few million years?) a part split. See figure 8 D. So the split is already covered with a huge layer of soil (like 10kn?) and above that a swallow sea (like .1km). Note also that they split is a very different way

So the main graphic of the press article is wrong in many aspects.
